Multiple sclerosis (MS), a rare and chronic central nervous system disorder resulting from autoimmunity, occasionally steps into the public eye when it strikes a well-known person (such as in 1999, when talk show host Montel Williams revealed his diagnosis). In neuroscience and immunology laboratories, however, the disease is always a major topic of investigation. Researchers… Read article →

Neurodegeneration is characterized by cumulative dysfunction and death of cells in selected areas of the nervous system.

The greatest burden of disease in the US, by number of individuals affected, is caused by Alzheimer’s disease (AD) (1). Characteristics of AD include… Read article →

Exosomes, endocytic vesicles ranging in size from 40–100nm, have revolutionized the field of cell–cell communication. Although they were first described in the 1980s, detailed analysis of exosome biogenesis, composition and function has occurred primarily within the past decade. The significance of exosomes is enhanced by the fact that exosomes transport packets of cellular information rather… Read article →

Diseases like Alzheimer’s, Parkinson’s and multiple sclerosis are the result of a dysfunctional nervous system. We know some of the factors that influence these… Read article →
